Now that you have your Reliability Resolutions for 2012 and will be using Advanced Diagnostics, Best Practices and New Technology to improve you reliability, it’s time for a […]
Wireless technology can have a huge impact on your process reliability. When a company develops a Reliability Centered Maintenance (RCM) program, it must first understand the current status of its reliability. It must also formulate the desired status. The process requires the collection of a significant […]
Along with advanced diagnostics and best practices, new technology can have a significant impact on your process control and instrumentation reliability. In the United States we pride ourselves on having some of the best technology which leads to good reliability and availability. However, technology that has been developed even in the last 10 years can […]
Industrial gas is used in many applications in a process plant. Nitrogen is used for tank blanketing or to eliminate oxygen in a combustible environment. Oxygen can be used in a process reaction or in waste water treatment to eliminate organic compounds. Industrial gases are generally part of utilities, which are […]
Pump reliability is one of the biggest rotating equipment challenges in a process plant. There are literally hundreds of pumps to monitor and maintain. There are three strategies which can be implemented to improve punp reliability, which will be explored here. These are redundant/spare equipment, transmitters with advanced diagnostics and
Since the creation of the first transmitter there has been a marked shift in technology. This includes the technology used for both transmitters and process control systems. The early pneumatic (3 – 15 psi) systems gave way to electronic systems (4-20mA), which eventually lead to digital protocols (HART, Foxcom, […]
Within a process plant there is all kinds of turbomachinery, including compressors, pumps and fans. They are generally steam driven and move a lot of fluid. They are large. They are expensive. The manufactures of turbomachinery will include basic controls to meet performance specification and safe operation. This presents a good opportunity to add […]
One of the largest challenges for the Environmental, Health & Safety (EHS) group is knowing when an event occurs. Keeping track of people within a process unit is challenging enough. Finding out when someone needs medical attention is critical. There is a significant difference in the outcome of an event based on how quickly a […]
In order to reduce installation and operational costs, process plants have ofter used RTDs or thermocouples without a transmitter for temperature measurement. This is especially true for high density temperature measurements like distillation columns, reactors and bearings on rotating equipment. However, there are a number of disadvantages to this strategy and high density temperature transmitters […]
Historically, reliability was realized through Preventative Maintenance (PM). It was routine to replace components on a time schedule based on best practices at the time. This included bearings, seals and lubrication. However, it was realized that these compenents could be perfectly fine and did not need replacement. Predictive Maintenance (PdM) soon replaced PM schedules. With […]
